JOSEPH FREDEROK FRADLEY, OF NEIV YORK, N. Y.

OPERA-GLASS.

SPECIFICATION forming part of Letters Patent No. 351,317, dated October 19, 1886.

I Application filed August 11, 1886. Serial No. 210,614. (No model.)

To 66% whom it may concern:

Be it known I, J osEPH FREDEnoK FRADLEY, a citizen of the United States, residing at New York, in the county of N ew York and State of New York, have invented a certain new and useful Improvement in Opera-Glasses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, in connection with the accompanying drawings, in which- Figure 1 is a perspective view of an operaglass constructed in accordance with my improvement. Fig. 2 is a partial sectional view through one of the barrels or body portions of the frame.

My improvement consists in forming the barrels or body portions of the frame of single thick tubular or hollow cylindrical portions of metal, which I prefer to ornament by hand-chasing.

Referring to the drawings, forming apart of this specification, A indicates the frame, which is of the usual and ordinary construction, consisting of tubes connected to each other by cross-bars or tie-pieces, and in the upper ends of which the top lenses are mounted, as usual. I prefer to construct these tubes of hard rubber or vulcanite, and the tie-bars of metal, although I do not confine myself to the use of such material. The lower or larger lenses are also mounted in two annular pieces of hard rubber or analogous material, and these two annular parts are connected to each other by a metallic cross-bar. The tubes carrying the top lenses are adjustable, to change the focus, by means of a thumlrnut or wheel mounted on a vertical rod, which is attached rigidly to the top cross-bar and moves freely through the intermediate one, as usual.

B B represent the barrels or bod y,of the frame, and {they consist of a single thickness of metal, preferably the precious metalsas gold and silver. I construct these barrels by cutting them of proper form, bending them structed with the barrels of hard rubber or analogous material, and they have also been covered with leather or velvet plush. \Vhen constructed of hard rubber, if the glasses should happen to fall, the barrels or cases are frequently broken, and the leather and velvet become rapidly worn and defaced, so that the glass soon presents an unsightly appearance. Glasses of this character, on account of the perspiration ofthe hands ofthe user or the smoothness of the barrels, and of gloves, when worn, are not only soiled, but are easily dropped and frequently broken or injured. All of these difficulties are obviated by my improvement, and, in addition, I am enabled to construct a most attractive and beautiful article of manufacture, as the gold or silver, oxidized or not, forms a striking contrast with the black rubber portion, and the facility with which these metals can be ornamented by chasing renders the glass a most attractive and desirable one.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

As a new article of manufacture, an opera glass the barrels or body portion of which are constructed of single thick metallic tubes, the external and exposed portions of which are hand-chased to roughen and ornament the same, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
